Thomas Aquinas
(c. 1224 - 1274)
Foremost theologian of the Roman Catholic Church, Thomas Aquinas sought to complement faith with the recently rediscovered philosophy of Aristotle. He received his “license to teach” in 1256, joining the faculty at the University of Paris as a professor of theology, but he spent much of the 1260s in Italy serving the papacy. He was canonized in 1323, forty-nine years after his death.
